Let me indulge. A TLD was designed to allow hierachial usage of the DNS system....

To make it easier to "find" a website, instead of using DNS numbers, we use "words"....Those words have to be entered verbatim to reach the website, unless you get redirected to MSN, and are able to find what you need....but clearly the TLD was design to make finding websites easy....Will having 50 new TLDs do that??? Your guess is as good as mine....but I got a feeling, the "duplicative factor" (krajewski, 2001) will be inherently problematic...
